HESI A2 Vocabulary 2023

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.

Correct Answer: B

Rationale: The correct answer is B: viral infection. HPV stands for Human Papillomavirus, a common sexually transmitted infection that can cause genital warts and certain types of cancers. This abbreviation specifically refers to a type of viral infection, not a blood condition (A), heart rate (C), or therapy (D). It is important to understand medical abbreviations to accurately interpret and communicate health information.

Correct Answer: A

Rationale: The correct answer is A: syringe. To aspirate fluid means to draw it into a syringe for further use or analysis. Syringes are designed for precise measurement and extraction of fluids. Beakers and test tubes are used for holding and mixing fluids, not for aspiration. Flange is a mechanical component and not used for aspiration of fluids.

Correct Answer: A

Rationale: The correct answer is A: Clumsy. 'Maladroit' means lacking skill or dexterity, often resulting in clumsiness. In the context of the sentence, it suggests that those who are maladroit (clumsy) should not become surgeons as surgery requires precision and skill. Explanation for other choices: B: Romantic - This choice is incorrect because 'maladroit' does not relate to being romantic. C: Untrained - This choice is incorrect as 'maladroit' is not specifically about lack of training, but about lack of skill or coordination. D: Self-conscious - This choice is incorrect as 'maladroit' does not imply being self-conscious, but rather lacking in skill or finesse.

Correct Answer: B

Rationale: The correct answer is B: Excessive. Superfluous means exceeding what is necessary or desired, therefore, it is synonymous with excessive. Maximum (A) means the highest possible level, not necessarily exceeding what is needed. Insipid (C) means lacking flavor or interest, which is unrelated to superfluous. Soggy (D) means wet or soaked, which is also unrelated to the meaning of superfluous.
